IMPROVEMENT IN HYDRANTS.

The Schedule referred to in these Letters Patent and making part of the same vward to open the hydrantfvalve, will be kept tight against said waste-opening, and prevent. thereby the escape of water through this waste opening dnring'the time the hydrant is kept open.

Figure I represents a longitudinal section of a hydrantrembodying my invention; and

In the accompanying drawing- A represents the valvechamber, attached at lm` to the water-pipe, and prvided with a cylindrical cup, D, on the top of which the pipe Eis attached.

In the lower part of this cylindrical cup D the valveseat b is arranged, and near tlie top of said cup D a neste-passage, C, is provided.

B is the .valveecylindeiy the lower end of which forms the valve fitting into the valve-seat l, and to the upper end of which the rod F for operating this valve-cylinder, to open or close the valve, is attached, the whole being arranged in the usual manner.

Figure II is a plan of the same, partly in section.

To the side of this valve-cylinder B a projecting surface, a, is provided, fitting the inner surface of the.

cylindrical cup D, and so arranged that, when the valve 'b is opened, this surface, a, will cover the opening of the waste-passage C, and will uncover or open the said opening as soon as the valve b is closed, for the'purpose of allowing the water remaining in the pipe Eto escape through this waste-passage C.

'lo this valve-cylinder B a. spring, n, is arranged. projecting on the side of said cylinder directly opposite the projecting surface a, so as to bear against the inner side of the cylindrical cup D, in such a inanner as to keep this surface a tight against the surface of the cup, and prevent thereby, when said surface a -covers the opening C, any'esca-pe of water through said passa-ge O.

WVhat I cla-im as myinvcntion,a1ul desire to secure by Letters Patent, is-

The combination of the hydrant-valve B, having the additional valve-surface a, to close and open the waste-passage 0,-- with the spring -n,arranged to keep the valve-surface a pressed close to the opposite surface of the pipe E, substantially as herein specified.
